Bacterial Counts and Physical Properties of Hatching Eggshells Sprayed with a Formaldehyde Solution.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Poultry companies must implement measures to sanitize hatching eggs and reduce the risk of bacterial infections associated with poultry management. Many of them use formaldehyde (FA) fumigation in their egg sanitization protocols, but its toxicity has led to recommendations for reducing its use. However, studies employing this approach with liquid FA solutions in poultry operations, particularly during the hatching egg sanitization stage, remain scarce. Our objective was to evaluate whether sprayable FA reduces bacterial contamination on eggshells and whether it causes changes in their physical properties based on the analysis of microstructure, percentage relative to egg weight, and thickness. FA solutions at 0.5, 1, and 2% inhibited bacterial growth in vitro and reduced the bacterial load on the eggshell surface while also causing severe damage to the shell structure. Our results suggest that companies using FA should be aware of the associated risks, as significant production losses may be linked to the shell damage caused by this compound.
